Madison is an open-source, collaborative document editing platform. While Madison can be used to collaborate on many different kinds of documents, the official version is being built with legislative and policy documents in mind.

Madison is a free tool that helps elected officials and everyday Americans solve problems together. Elected officials post drafts of policy documents on the site so that you can weigh in and stay informed about the issues you care about most. Madison brings policymaking out into the open, and gives you a voice in your government and a way to hold it accountable.
